UnicodeEncodeError: 'charmap' codec can't encode character '\U0001f937' in position 0: character maps to <undefined>

Question

我目前正在开发一个从 subreddits 中获取数据并将其写入文本文件的应用程序。启动我的脚本时，我运行出现以下错误：

  File "my_file.py", line 35, in <module>
    data.writelines('parent_id: '+ str(comment.parent()) + 'body: '+ str(comment.body) + "\n")
  File "C:\Users\supre\anaconda3\envs\learn-python\lib\encodings\cp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode character '\U0001f937' in position 0: character maps to <undefined>

这是我的代码：

import praw


reddit = praw.Reddit(client_id = 'my_client_id',
                     client_secret = 'my_client_secret',
                     username = 'my_username',
                     password = 'my_password',
                     user_agent = 'my_user_agent')
                    
subreddit = reddit.subreddit('news')

hot_python = subreddit.hot(limit=50)

data = open('data.txt','w')
for submission in hot_python:
    if not submission.stickied:
        print(20*'-')
        print('TITEL: '+ submission.title)
        
        
        submission.comments.replace_more(limit=0)
        for comment in submission.comments.list():
            print(30*'+')
            print('parent_id:', comment.parent())
            print(comment.body)
            if len(comment.replies) > 0:
             for reply in comment.replies:
                    print('REPLY:')
                    print("\t"+reply.body)
                    print(reply.parent())

    
            data.writelines('parent_id: '+ str(comment.parent()) + 'body: '+ str(comment.body) + "\n")
data.close()

是不是我做错了什么？如果是这样，如果有人能告诉我我做错了什么并帮助我解决这个问题，我会很高兴。

提前感谢您的每一个建议和帮助:)

尝试：

data = open('data.txt','w', encoding='utf-8')

UnicodeEncodeError: 'charmap' codec can't encode character '\U0001f937' in position 0: character maps to <undefined>
